2.1 System Requirements

To install and use your TX 2000/TX 3000 board, your system must have:

2.2 Configuring the Hardware
Caution:

The TX 2000 and TX 3000 boards are shipped in protective anti-static containers. Leave the boards in the containers until you are ready to install them. It is recommended that you wear an anti-static wrist strap connected to a good earth ground whenever you handle the board. Take care not to touch the gold fingers which plug into the ISA bus connectors.

2.2.1 Setting the Memory Address

TX 2000/TX 3000 boards use a high speed dual port static RAM and a memory-mapped control and status register to facilitate communications between the CP and the host personal computer.

TX 2000/TX 3000 boards require an 8 KB block of memory in the first 1 MB of the host's memory space. TX 2000 boards come set to 0xD6000 as the starting address; TX 3000 boards come set to 0xDA000 as the starting address, but either board can set for any available segment between 0x80000 and 0xFF000. Use a system diagnostic program to determine an unused memory segment.
WARNING:

Video adapters, network adapters and ROMs also occupy segments in this region

Note: Many systems reserve the range 0xE0000 through 0xFFFFF for system functions.

Figure 3. Memory Address DIP Switches on a TX 3000 Board



After establishing a free memory segment, use the following chart to set the DIP switch on the TX 2000/TX 3000 board to the desired memory segment. Set all switches up to ON, then push the switches down for the positions marked with an underscore ( _ ) in the following table. The Memory Address Select DIP switch (S1) is located near the lower center of the TX 3000 board. Figure  3 is set for address CC00. The location is slightly different on the TX 2000.

2.2.2	 Setting the Interrupt Request





TX 2000/TX 3000 boards require the use of an interrupt request (IRQ) signal on the ISA bus. A jumper is used on the TX 2000/TX 3000 boards to select the IRQ used to interrupt the host personal computer. The default setting is 10 for the TX 2000 boards and 11 for the TX 3000 boards. Use a system diagnostic program to determine an unused IRQ signal. 







WARNING:







Sharing an IRQ with other devices is not supported.



















TX 2000/TX 3000 boards are able to share an IRQ with other TX 2000/TX 3000 boards. The host software must be configured for this option. TX 2000 boards must also be jumpered for the shared interrupt option (see Section  2.3.2). Figure  4 shows the default IRQ setting for a TX 2000 board. 





Figure 4.	 Interrupt Request Jumper Settings on a TX 2000 Board (Default)




The jumper position labeled NO is used to disable the ISA bus on the 
TX 2000/TX 3000 board for stand-alone operation.

2.3	 TX 2000/TX 3000 Jumper Settings





The following subsections provide a description of the jumper settings available on the TX 2000/TX 3000 boards, as well as the location of each jumper.






2.3.1	 Setting the Boot Options Jumpers (TX 2000 only)





JP1 determines the boot type (dual port RAM or flash memory) for the TX 2000 board. 



Dual port RAM (DPR) boot is the default, vertical position. Boot files originate from the host via dual port RAM. 



Place the jumpers horizontally for flash memory boot. Boot files originate from flash memory on the TX 2000 board.



JP2 sets the boot device size.



The default jumper setting is >8 for DPR boot. For flash memory boot, remove the jumper entirely. The 32 option is reserved and should not be jumpered.



Figure  5 shows the location of the boot options jumpers and their default settings.





Figure 5.	 Default Boot Options Settings for a TX 2000 Board






2.3.2	 Setting the Interrupt Type Options Jumper (TX 2000 only)





JP9 defines the type of interrupt used by the TX 2000 board.



The TX 2000 board is set for Shared Interrupts by default, in which a jumper is placed on the upper and middle pins. To set the Standard Interrupt option on the TX 2000 board, place a jumper on the middle and lower pins.



Figure  6 shows the location of the jumper, as well as the default setting.





Figure 6.	 Shared Interrupts Setting (default) for a TX 2000 Board






2.3.3	 Setting the MVIP Bus Termination Option Jumper





When a series of Natural MicroSystems ISA boards are connected via the MVIP bus, the end boards must have jumpers on the MVIP bus termination pins (JP14 and JP16).



The JP14 and JP16 pins do not have jumpers, by default, indicating that the
TX 2000/TX 3000 board is not the terminating board in an MVIP chain.



Connect the JP14 pins together and the JP16 pins together using two jumpers to set this board as an MVIP bus terminator.

2.4	 Installing the Hardware 







Caution:







If you are not familiar with installing expansion boards into your system, refer to your computer's "Guide to Operations" for specific installation instructions. 





















To install a TX 2000/TX 3000 board in your system:


    


  1. Determine a free memory segment in computer's memory map and set the Address Select DIP switches (see Section  2.2.1).
    

    

  2. Determine a free interrupt request signal and set the IRQ Jumper (see Section  2.2.2).
    

    

  3. Read Section  2.3, TX 2000/TX 3000 Jumper Settings. All TX 2000/TX 3000 boards are shipped with the default configurations set. Make any necessary changes to the jumper settings as required by your system.
    

    

  4. Switch off the computer and disconnect the power cord from the back of your system unit.
    

    

  5. Arrange your TX 2000/TX 3000 board and other MVIP-90 boards in adjacent ISA bus slots. Make sure each board's ISA bus connector is seated securely in a slot.
    

    

  6. Connect your MVIP-90 boards to the MVIP-90 bus cable. 
    

    
Note:  If you are using Natural MicroSystems ISA MVIP-90 boards, make sure then end board are terminated, as described in Section  2.3.3.


  7. Making sure the top of the board's bracket is aligned with the hole on the top of the expansion slot, replace the screw which previously held the blank slot cover.
    

    

  8. Connect the Configurable Serial Pod with Pod Cable, if required
    

    

  9. Connect Ethernet cable and or T1/E1 cables, if required
    

    

  10. Replace the cover and connect the computer to its AC power source.
    







2.5	 Installation Troubleshooting Information





The most common problems with installing the TX 2000/TX 3000 board are caused by conflicting settings for the address ranges and IRQ settings with other devices on your ISA bus. 



If you do not have device configuration information easily available, there are a number of software tools used to query the ISA bus to determine available addresses and IRQs. WinMSD (provided with Microsoft Windows NT) is an example of such a tool.
